Ensure a good sleep is essential especially during stressful activities on the mountain. So, well what kind of sleeping bag you need to not perform a mistaken purchase. Cold or heat and sweat a lot during the night to the point of not being able to sleep well doesn’t mean, necessarily, that you bought a sleeping bag. Can demonstrate only that the sleeping bag you are using is not the most appropriate for your situation or location where you are.
One aspect that determines the ability to withstand a cold sleeping bag is the kind of filler that it uses. Inform yourself about what is the average temperature of the place where you will camp, and what is the time of year, and try to take a bag that supports at least five degrees to the temperature of the place. Today, the market offers various alternatives of fillers. Check out this website.
Goose feather – widely used in lower temperatures, the sleeping bags filled with goose feather are very comfortable and more compressible than synthetics. This can be a great advantage for those who need to carry the bag inside the backpack. Despite being more expensive than synthetic, they last about four times more than the first. Have a better relationship between the ability to keep warmth and weight, so it is recommended for very cold, with snow, for example. However, to warmer locations he is not appropriate. In addition, its thermal insulation and ability to maintain heat if disable when the bag is wet. Not to mention that it takes a long time to dry. Whereas even in the driest places the body always produces some moisture, it is important to leave the bag to ventilate and dry before putting it away in the bag. But beware of excess Sun. look for a place in the shade.
Solid Fiber -Are usually made of polyester or nylon. As well as the natural fibres, solid fiber bags do not allow the air input and output, so it retains a lot of heat. The difference is that they do not retain water and keeps the heat even if wet. They also dry quickly. Are usually bags of lowest cost, but its weight is relatively large compared to hollow fiber or goose feather. Are advisable only for car camping, and you don’t have to carry the bag in his backpack.
Plume -is the material that allows for more heat. It is also the most compressible and can be reduced to a small volume. In addition, quickly regains its softness, and its ability to heat, when extended. These qualities make the feather an excellent insulation for use in cold climates. However, the plume loses all its qualities of insulation when wet and it is impossible to dry it in the mountains, making it a bad choice of insulation in humid climates. It is common to mix with goose feather plume not to raise too the final cost of the product. The higher the proportion of feather, the higher the quality of the insulation.
Hollow Fibres – the technological development allowed the creation of materials which made sleeping bags each time lighter, warm and resistant. Hollow fibers are the latest evolution in fiber. The integrated system for micro filaments allows for greater circulation of hot air, favoring the retention and the isolation of air layers. There are hollow fibers of one, four or seven holes and the higher the number the higher your ability to heat up. Are very fibers thinner than a hair, creating a tangle of wires can be compressed and back to normal. These same fibers create air pockets that make them very effective. Depending on the manufacturer, vary in dimension (short or long), format, size of holes in fibre, density, weight and thickness.
The most modern of sleeping bags & Trails Directions using a revolutionary hollow fiber called micro filaments, Microtech only 0.7 denier (Denier is a measure of thickness of yarn. A hair has 20 denier. The higher the number, the thicker wire), which can hold more air, similar to that achieved with the feathers and goose down. She warms even wet, doesn’t retain as much water, leaving dry faster than other fibers, and has a good thermal insulation with less volume, resulting in a much more compact sleeping bag for transport. An example is the Micro-Feather, sleeping bag ideal for the climate of the Brazilian mountains or traveling abroad at low altitudes.
It’s worth remembering that there are other factors may influence the heating capacity of the sleeping bags. For example, how is sewn bag. The Micro bag-Feather, Trails & Directions, uses the loose-system shell, English name which means that the bag does not have seams in front and back, thus avoiding heat loss by micro-holes made by sewing needles. The filling of the bag is placed coated by a thin layer of insulating fabric, breathable, arrested just on the sides.
